LAMP.

Specification of Letters Patent.

Application filed June 3, 1908.

Patented June 15, 1909.

Serial No. 436,385.

To all whom it may concern:

Be it known that I, PAUL KRASTIN, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Lamps, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The invention relates to lamps more particularly designed for use onmotor vehicles, and the invention consists in the novel features ofconstruction as hereinafter set forth.

In the drawings- Figure 1 is a central section through the lower portionof the lamp; Fig. 2 is a section in a plane at right angles to Fig. 1through the upper portion of the lamp; Fig. 3 is a section through thisupper portion in the plane of Fig. 1. Fig. 4 is a section on line x-x,Fig. 2; and Fig. 5 is a plan view of the latch.

A is the font and B is the upper or lantern portion of the lamp. Thesetwo portions are detachably secured to each other by means of springlatches O preferably arranged upon opposite sides of the font. More indetail the lantern portion B is provided with an annular flange D whichsurrounds and fits a bearing E upon the font A and is connected by aneck portion F of reduced diameter to a cylindrical portion G. The neckportion F is cut away at opposite sides to form the apertures H, throughwhich the latches C are inserted, while the uncut flange portion E formsthe keeper for engaging with these latches.

The font portion A has arranged therein a vertical cylinder I whichforms the oil rece ptacle, and outside this cylinder are spaces in whichthe spring shanks ofthe latches C project. These shanks are preferablysecured at their lower ends to the cylinder I, as illustrated. The upperportion of the latches C are preferably formed, as shown, with thecentral portion O struck outward to form the shoulder or detent forengaging with the flange E. Thus to engage the font with the lanternportion, it is merely necessary to insert the burner within the flange Ewith the latches O in registration with the apertures H, and to thenpress the memberstogether until the detent C springs over the upper edgeof the flange E. To disengage these parts, the operator may press withthe thumb and nger upon the opposite latches C, which will spring theminward suiiiciently to disengage the detents from the flange E andpermit the separation of the parts.

The cylindrical portion G of the lantern is provided at its forward endwith the enlarge ment G for receiving the bulls eye, and at its rear endwith a concave reflector J. Intermediate these parts is arranged adellector K which surrounds an upwardly projecting portion of the neck Fand is bent downward at its opposite ends K.

L are air inlet apertures for the cylindrical portion G, which are to acertain extent shielded by the portions K ofthe deflectcr so as to avoiddrafts which would interfere with the flame. The neck F is also providedwith apertures M which open into the space beneath the deflector K andapertures N in the cylindrical portion G also open into this space. Thespace just referred to communicates with the interior of the lanternthrough the annular slit O between the deflector K and the upwardlyprojecting portion of the neck.

The arrangement just described is intended to provide the necessarydraft for the lamp without danger of creating drafts to interfere withthe light.

Upon one side of the cylindrical portion B is a door P, which ispreferably hinged at its lower edge, as indicated at Q, and at its upperedge is provided with a latch R. The detent on this latch is preferablystruck up in a similar manner to the construction of the latch O, butthe spring shank S eX- tends transversely and is secured at one end tothe upper flange T of the door. Intermediate the ends of the shank is aknob or button U which projects through an aperture in the flange D andpermits of depressing the latch to disengage the same, and a secondoperating knob V is arranged at the free end of the shank. Thus bydepressing either of these knobs the latch may be disengaged.

With both of the latches C and R the metal is rounded to a point so asto form a guide for entering the latch in engagement with its keeper. v

What I claim as my invention is:

l. The combination with a font, of a lantern having an annular flangefitting over a portion of said font, said flange having an aperturetherein and a spring latch on said font insertible Within said flangepassing out through said aperture and engaging the upper edge of theflange.

2. i The combination with a font, of a lantern having an annular flangefitting over a portion of said font, and a reduced portion above saidflange having an aperture therein, a spring latch secured to said fontand projecting upward therefrom, said latch during the engagement of thefont and lantern passing within the flange of the lantern and outthrough the aperture in the reduced portion thereof and engaging withthe upper edge of said flange.

3. The combination with a font having a fpartition therein forming acentral oil well, o a spring latch having its shank extending in thespace between said partition and the outer wall of the font, a lanternhaving an annular flange fitting a portion of said font and engageabletherewith over said spring latch, the upper edge of said flange formingthe keeper for engaging the latch.

4. The combination with a font, of a lantern having a portion forengaging said font and a neck portion projecting upward therefrom intothe inclosed space within the lantern, a shield surrounding said neckportion and forming a narrow annular slit therebetween, and means belowsaid shield for admitting the external air to the space therebeneathwhereby it will pass upward through said annular slit. y

5. The combination with a font, of a lantern having a cylindrical closedcasing, a tube projecting upward into said casing, a shield surroundingthe u per end of said tube and separated there rom by a narrow annularslit, the ends of said shield being bent downward, means for admittingthe external air into said tube and beneath said shield, and means foradmitting air into the closed casing at a oint protected by' thedownwardly bent end of said shield.

- In testimony whereof l affix my signature in presence of twowitnesses.V
